UNITED STATES PATENT DUMPlNG-CAR.

SPECIFICATION forming part of Letters Patent No. 490,3.24,'dated January24, 1893.

Application Filed April 20, 1892.

To a-ZZ whom t may concern.-

Be it known that I, EDWARD A. TRAPP, a citizen of the United States, anda resident of Paterson, in the county of Passaic and State of NewJersey, have invented certain new and useful Improvements inTransportation and Dumping Cars, of which the following is aspecification.

The invention relates to improvements in transportation cars and meansfor operating the gates or doors of same, and consists of a car composedof compartments separated by a definite space and having doors whichincline downward toward said space, on oppo site sides of which thevertical facin g portions of the car are provided with doors or gatesthrough which the compartments are discharged of their content-s andwhich are adapted to be operated by compressed air through mechanismunder the direct control of the engineer on the locomotive. Inaccordance with my invention all the cars of the train may be dischargedof their contents at one time by the engineer or any number of the carsmay be'thus discharged. The cars which form the subject of a part of theinven-V vention are intended for transporting coal to definite stationswhere they are run upon elevated tracks and dump the coal' through thesame; but itis to be understood that the cars are not limited in theiruse to the carrying of coal or any special commodity.

The invention will be more fully understood from the detaileddescription hereinafter presented, reference being had to theaccompanying drawings, in which Figure l is a side elevation of aA carconstructed in accordance with and embodying the invention; Fig. 2 is anenlarged top view partly broken away of same; Fig. 3 an enlargeddetached side elevation of the middle portion of the car, showing thespace between the compartments and the mechanism therein for operatingthe discharge gates or doors;

Fig. 4 a vertical transverse section of same on the dotted line 4=4= ofFig. 3; Fig. 5 adiagram of the car showing dimensions for a carryingcapacity of thirty-six tons of coal; Fig. 6 a central verticallongitudinal section of a part of the middle portion ot the car showinga modified construction of the discharge gates or door and levermechanism for opening Serial No. 429,854 (No model.)

and closing the same; Fig-.7 a detached view of the inner end of one ofthe compartments of the car showing a further modified forni ofdischarge gate and operating mechanism therefor, and, Fig. S is adetached side elevation of the compressed air cylinder forminga part ofthe gate operating mechanism.

In the-drawings A, designates the car; B the bed frame thereof, and Cthe trucks.

The body of the car A consists of the compartments D, E, separated by acentral space F and having the doors G which incline downward towardsaid space. In the vertical facing inner ends H of said compartments D,E, are provided the discharge doors or gates I, J, whose lower edges arein line with the lioors G and which doors are adapted to be operated bymechanism located in the space F, as hereinafter described. The doors orgates I, J, may be of any desirable form or construction, and hence asexamples there are illustrated in the drawings both sliding and hingeddoors, with appropriate lever mechanism for operating them, Figs. 4 and7 showing the sliding doors and Fig. 6 hinged doors. The iioors of thecompartments D, E, incline downward toward the doors or gates I, J, andwithin the corners at theinner ends of the compartments are provided theinclines K, which prevent the coal settling in said corners and directthe material to the discharge doors or gates.

The compartments D,E, are connected and the whole structure strengthenedon opposite sides by the inclined beams L diverging downward from acentral point at the top of the car and by the longitudinal supportingbeam M located between and joining said beams L; and said compartmentsare further connected and strengthened by the beams N at opposite sidesof the lower inner ends thereof and extending across the space F. Stayrods O are also provided, as shown in Figs. l and 3, and extend downwardand outward from the upper part of the space F through the beams L, M,and longitudinal beams P passing along the outer edges of the floor offthe compartments. The upper adjoining ends ot the beams L are connectedby the transverse rod Q, and the opposite sides of the compartments E,D, are connected at about the middle of their length by the trans- IOOverse rods R. From the central transverse rod Q there extends downwardand outward the central diverging inclined beams S, which are secured bya cap T at their upper ends and at their lower ends are bolted tothecentral longitudinal beam V extending through the compartments on a linewith and forming a part of the bed frame B.

The car constructed as above described forms one part of the invention,and a further portion of the invention involves the meanshereinaterdescribed fcroperating the discharge doors or gates I, J, iuth`e inner facing ends II of the compartments D, E.

The drawings present several systems of levers for opening the dischargedoors or gates I, J, and hence the mechanism shown in Figs. l, 2, 3 and4 will iirst be described. Upon reference to said Figs. l to t it willbe seen that within the yspace F between the compartments D, E, issupported a compressed air cylinder 'W which is in communication througha pipe connection Xhaving a cut orf valve Y with the longitudinal pipe Zextending the entire length of the car, and being properly supported atgiven intervals, as shown in Fig. l. The pipe connectionXleads to thelower side of the piston in the cylinder W', and hence upon thecompressed air entering said cylinder the piston and its rod a will beelevated. and set in motion the levers by which the gates I, J, areopened. To the upper end of the piston rod a is secured the cross head badapted to move between the guides d (see Fig. 4) and having connectedwith its ends the outer ends of the levers e, whose inner ends aremounted on the shaftf sustained in hangers g, and which levers at eachside of the space F carry the supplemental levers h and the rods 'ileading to one of the discharge doors or gates. The supplemental leversh at their outer ends are mounted on the shaft; supported in hangers.76, and at their inner ends said levers at opposite sides of the spaceF are connected with the rods m extending to the other of said dischargedoors or gates; thus at each side of the space F there are provided thelevers e, 72 which are connected together by the loose bolt n and carrythe rods t', m, to which the discharge doors are secured. Upon thepiston rod a being elevated by the admission of compressed air to thecylinder WV the levers e, h at each side of the space F will be elevatedand simultaneously lift the discharge doors or gates I, J, permittingboth compartments D, E, to at once dischargetheir contents, the latteroperation being automatic owing to the inclined floors G. During thedischarge of the coal or other material from the compartments D, E, thetrack rails will be kept clear by the inwardly inclined guards q, whichaid in directing the coal inward that it may fall between the ties tothe proper place of deposit. Upon the pressure being relieved from thecylinder NV, the piston rod a, levers e, h, and gates I, J, will oftheir own specific gravity descend to their former closed position.

It is obvious that various systems of levers intermediate the piston roda andthe discharge gates or doors I, J, could be used with good effectand hence the Vinvention is not confined to the special form ofleversabove described. As examples of further forms or' gate operatinglevers reference is made to Figs. 6 and 7, which show both hinged andsliding doors with appropriate connecting mechanism. In Fig. 6 thecylinder W appears in an inverted position with its rod o carrying thepair of levers t connected at their lower end with the lower edge of thedoors I, J; and upon the elevation of the rod a the levers t will openthe doors I, J, as denoted by Jfull lines, while upon the lowering ofsaid piston rod a the doors I, J, will close and be locked by the leverst coming into a horizontal position in line with each other, asindicated by dotted lines. rIn Fig. 7 the arrangement is such thatthrough the rocking lever w the sliding door I will be 'opened on thelowering of the piston rod a and close by its own specific gravity,returning the rod a to its initial upward position. Two discharge doorsmay be used at each side of the space F, or one door or a greater numberthan two as may be preferred, and said doors may be opened by the forceof the compressed air and allowed to close ot their own specificgravity, or they may be both opened and closed under the positive actionof the cornpressed air, as may be desired.

In Fig. S is illustrated the cylinder WV having two pipe connectionsleading from two supply pipes 0c, y, to the opposite sides of the pistonone connection being to move the piston in one direction to open thedischarge gates and the other to move said piston in the oppositedirection to close said gates.

It is proposed to lit each car with the compressed air mechanism, andcouple together the meeting ends of the longitudinal airpipes Z of theseparate cars of the train, in order that the engineer in his cab mayhave full control of the same and by simply turning a lever may applythe compressed air and open all ol' the doors or gates I, J, of theentire train, thus discharging all of the cars at one time. Theconnections whereby the engineer may apply and eut ed the compressed airare not shown, since they are well understood and will be such as he nowemploys in connection with the air brakes. In case it should be desiredthat some one or more of the cars of the train should not be dischargedwhile the others are discharging, the saine may remain unaffected bysimply turning the valves Y in the connections X of said car or cars,thus cutting oft the compressed air therefrom and leaving their doors I,J, closed.

From the foregoing description it will be seen that I have provided anew transportation cai1 and also novel economical and effective meansfor opening and closing the dis- IOO ITO

charge doors of same. The importance of enabling the engineer to controlthe discharge of the entire train Without leaving his cab will bereadily appreciated, and this object my invention fully accomplishes inits introduction of compressed air with suitable connectionsforopeningoropeningandclosing the discharge doors or gates. rIhis latterportion of the invention `will also prove of importance as applied tothe opening of doors, gates and like devices other than thoseillustrated in the drawings, and hence I do not limit this portion ofthe invention specifically toa transportation car. Neither do I connethe special form of car shown to the use of the compressed air mechanismfor operating the discharge doors or gates, since the carin itself isnovel. The space F between the compartments D, E, may if desired becovered to protect the gate operating mechanism.

What I claim as my invention and desire to secure by Letters Patent is:

1. The transportation car'having the com-v partment provided with theinclined door G and the discharge door, combined with 'the compressedair cylinder connected with said door for operating the same, and thesupply pipe for compressed air to said cylinder; substantially as andfor the purposes set forth.
